Protests against President Nixon's war policy continued to mount this week as antiwar groups prepared for a counter on January 20, announced other future actions and issued vitriolic statements.

The three largest antiwar groups the National Peace Action Coalition, the Student Mobilization Committee and the People's Coalition for Peace and Justice--have endorsed the January 20 demonstration in Washington.

The week's Harvard protests began Saturday with five Faculty memebers urging Congress to "take immediate action to withhold funds for the further prosecution of the war," on behalf of 15 professors here and 216 others around the country.

Their statement denounced the "savage and irresponsible use of American power" in the war, likening it to Japanese terror bombing of Shanghai during World War II and the Nazi attack on Guernica during the Spanish Civil War.

"Pearl Harbor is peanuts compared to what we've done," added John K. Fairbank '29, Higginson Professor of History and director of the East Asian Research Center and one of the endorsers.

Harvey G. Cox. Thomas Professor of Divinity, arrived in London Monday with five antiwar clergymen for a five-day tour to mobilize antiwar sentiment in the European religious community.

The group hoped to end its visit with an audience with the Pope today.

The January 19th Committee, an ad hoc antiwar group, announced plans Tuesday for a massive lunch-hour demonstration in Boston next Friday Service Committee and Medical Aid to Indochina announced a January 20 benefit concert for North Vietnamese hospitals destroyed by the war.

The planist Lorin Hollander and Robert Koff, chairman of the Brandeis University Music department, will appear at the five-dollar concert in Sanders Theater.
